  OpenZeppelin Contracts is a library for secure smart contract development.

  

I modified my code to use EIP712 to require an authorized wallet to also sign in order for an NFT to be minted. I based this off of this: https://github.com/OpenZeppelin/openzeppelin-contracts/blob/7e814a3074baa921db584c180ff6e300cdec8735/contracts/token/ERC20/extensions/ERC20Permit.sol. This is an example of someone calling a smart contract containing this ERC20Permit.sol code https://github.com/Uniswap/v3-periphery/blob/main/test/shared/permit.ts. This particular ERC20Permit.sol code is designed to allow an account to approve ERC20 spend limits without spending gas fees but the same underlying mechanisms could be applied to my use case.

This is a next.js repo I made to mint an NFT from the above smart contract https://github.com/ChristianOConnor/nft-sig-verify-mint-eip712-style. My running instance of the above smart contract is 0x509de904bB414701A1Fad31370c28631CcF5e4A6. I hardcoded this into the next.js app. The next.js app requires the private key for the authorizedAccount (which is 0x82d6d541FEB42aa62A7C6E0E8045Dc0458ff648c). I have the line:
